Protection Functions:
1.
Max. Amps switch:
This switch on the control panel allows the user to optionally select the maximum
current (Amps) the unit will deliver to the attached appliances without automatically shutting off. Use a
small screwdriver to select 2A, 5A, 10A or 15A (factory default).
Setting Procedure:
a.
Use a small screwdriver to select 15A (factory default setting).
b.
Connect all appliances to the unit and operate appliances at their highest level.
c.
Press the Volt/Amp key to observe the current value (Amps) consumed by appliances.
d.
Turn off the connected appliances and turn the unit off.
e.
Use the small screwdriver to set Max. Amps to the next highest value. For example if the LCD
display indicates your appliances are consuming 6.12 Amps at their highest level, set the Max.
Amps switch to 10A. In the future, if the attached appliances begin to draw a higher than normal
load and exceed 10A of current, the unit will go into Over Current Mode (see below), shut off power
and help protect the connected appliances.
f.
Resume normal operation.
2.
NFB (No Fuse Breaker)
The NFB will activate when the unit is subject to overload. Press the NFB to
reset and restart.
3.
Over Current mode:
When the current load presented by the connected appliances exceeds the
setting on the Max. Amps switch, the unit will switch to Over Current mode. The power will be switched
off to the 10 outlets. The red LED in the OFF switch will flash. The LCD will display the protected current
value. The Over Current icon will flash and the audible alarm will sound. Remove the appliance(s) which
is causing the over current power draw or readjust the Max. Amps value to a higher setting. Then press
the OFF key and then the ON key to turn the power back on.
4.
Abnormal Voltage mode:
When the voltage presented at the wall outlet if over or under the normal
voltage range, the unit will switch to Abnormal Voltage mode. The power will be switched off to the 10
outlets. The red LED in the OFF switch will flash. The LCD will display the protected voltage value. The
Abnormal Voltage icon will flash and the audible alarm will sound. When the AC line voltage delivered
by the wall outlet returns to a normal range and is stable for at least 3 seconds, the unit will switch back
to normal mode and restart power immediately. The unit will enter Abnormal Voltage mode if the AC line
voltage is over normal by 13% or under normal by 18%. The unit will switch back to normal mode when
the AC line voltage returns to +10% to -15% normal.
5.
Over Load mode:
The unit contains dual redundant over load protection circuits; an electronic control
breaker and a traditional NFB (No Fuse breaker).
a.
Electronic control breaker: When the current load presented by the connected appliances exceeds
15 Amps, the unit will switch to Over Load mode. The power will be switched off to the 10 outlets.
The red LED in the OFF switch will flash. The Over Load icon will flash and the audible alarm will
sound. Remove the appliance(s) which is causing the over load power draw. Then press the OFF
key and then the ON key to turn the power back on.
b.
NFB (No Fuse breaker): When the NFB detects an over load condition, it will set and cut off power
to the unit. This will cut off power to the 10 outlets as well as the LED
’
s and LCD display panel. The
unit will be totally without power. Check and remove the appliance(s) causing the over load, and
then press the NFB button to reset the breaker.
